Aortograms of 102 consecutive patients with abnormal aorta were analyzed. Three patterns of aortic dilatation were identified: I (n = 55), the largest aortic diameter was at level 2 (normal pattern); II (n = 39), the aortic diameters increased from levels 1 to 4; III (n = 8), all ...
which begins at the level of theaortic valveand extends to the sinotubular junction. This portion of the ascending aorta is the widest and measures about 3.5 cm in diameter. The ascending aorta extends to the origin of theinnominate artery. Theaortic archbegins at the innominate artery and ends...
The normal diameter of the ascending aorta has been defined as<2.1 cm/m2and of the descending aorta as <1.6 cm/m2. The normal diameter of the abdominal aorta is regarded to be less than 3.0 cm. The normal range has to be corrected for age and sex, as well as daily workload. Can ...

22 Aortic size was measured in the parasternal long axis view at end diastole at 4 levels: (1) aortic annulus, (2) sinuses of Valsalva, (3) sinotubular junction, and (4) ascending aorta (2-3 cm above the sinotubular junction at the maximal visualized diameter). Aortic measurements, ...
The flow of blood through vessels is pulsatile in nature, which for adult humans leaves the heart with a veloc- ity at peak systole in the range150 < U < 175 cm/s , via the ascending aorta of diameter 3 < D < 4 cm12. Using standard values of blood viscosity and density, as ...
CT revealed a large low-density area within the abnormal- ity, measuring 70 × 74 mm in diameter, which indicated circumferential perigraft fluid collection around the entire length of the graft in the ascending aorta (Fig. 2B, C). This fluid accumulation was 15 mm larger ...
tearing opening in the descending aorta accounts for about 30% of all aortic dissections. Aortic aneurysm refers to pathological expansion of the aorta which exceeds 50% of the diameter of the normal blood vessel. It can occur in the aortic sinus, ascending aorta, aortic arch, descending ...
A method and device for occluding a patient's ascending aorta, maintaining circulation of oxygenated blood in the patient and delivering cardioplegic fluid to arrest the patient's heart. An aortic occlusion catheter has an occluding member for occluding the ascending aorta. The aortic occlusion cath...
rAAD incidence was observed to be higher among patients with an ascending aortic diameter 鈮 4.0 cm (4.8% vs 0.9% for ascending diameter <4.0 cm); P = .047. Incidence was also higher with proximal landing zone in the native ascending aorta (zone 0) 6.9% (2/29) versus 1.4% for all...
